The tax-to-GDP ratio varies significantly between Member States, with the highest share of taxes and social contributions in percentage of GDP in 2018 being recorded in France (48.4%), Belgium (47.2%) and Denmark (45.9%), followed by Sweden (44.4%), Austria (42.8%), Finland (42.4%) and Italy (42.0%).

At the opposite end of the scale, Ireland (23.0%) and Romania (27.1%), ahead of Bulgaria (29.9%), Lithuania (30.5%) and Latvia (31.4%) registered the lowest ratios.
At 32.7% in 2018, Malta's total revenue from taxes and social contributions was slightly lower than the 32.9% registered in 2017. It is interesting to note that in 2002, Malta's total revenue from taxes and social contributions stood at 30.8% while it then rocketed up to 34.2% in 2007.
